This is an original PING Scottsdale Anser putter. Like all Scottsdale putters, this hard to find Anser was made between 1965 and 1967. The Anser is, of course, perhaps the most celebrated putter design in history, and the early Scottsdale versions are coveted by collectors. Stamped "PING GOLF CLUBS" and the Scottsdale address in the cavity. Excellent condition.
